The even greater mystery is what they were thinking with the ES20! They removed a few features, and maybe had the interns working on the FR mode and messed it up.
Then they put back in the ES15 the features they removed from the ES10-to-ES20 and added some more. And to confuse the consumers even more, the model numbers are out of sync....
If I knew at purchase time the ES20 couldn't pause FR mode but all the other models I was considering could, then I would have probably waited to find either an ES10 or a Pioneer 22x/23x.
I never used an ES10 so I can't really compare them other than compare the user manuals
